Ingersoll Cutting Tools 6212266 Turning Insert CNMG432PC

Product Description

The INGERSOLL CUTTING TOOLS 6212266 is a CNMG432PC-style solid carbide turning insert in grade TT8105B, designed for external and internal turning operations on steel workpieces. The insert features a multilayer CVD coating system combining TiCN, Al2O3, and Titanium Nitride for heat resistance and extended tool life in continuous and interrupted cuts. With a neutral hand orientation and a negative rake geometry, it seats in standard CNMG clamp-style toolholders. The 80-degree diamond shape and PC chip breaker geometry promote controlled chip formation across a range of depths. Machinists and CNC operators working in job shops and production environments rely on this insert for general-purpose steel turning.

This insert is intended for primary use on steel workpieces, consistent with ISO material group P classification. The PC chip breaker is suited for light to moderate finishing and semi-finishing passes. With a maximum depth of cut of 0.196 inches and a 0.031-inch corner radius, it handles fine surface finish requirements while maintaining chip control. Four cutting edges per insert reduce per-edge tooling cost on high-volume turning programs. Compatible with standard CNMG clamp-top toolholders accepting a 0.5-inch inscribed circle insert.

Key Features

• Multilayer CVD coating: TiCN, Al2O3, and Titanium Nitride for wear and heat resistance
• 80-degree diamond insert shape with negative rake for stable cutting forces on steel
• PC chip breaker geometry for controlled chip formation in finishing and semi-finishing
• Four usable cutting edges per insert for extended tooling economy
• 0.031-inch corner radius supports good surface finish on turned diameters
• Neutral hand insert fits standard CNMG clamp-style toolholders without hand restriction

Compatibility

Designed for use in standard CNMG clamp-top toolholders accepting a 0.5-inch inscribed circle insert. ISO equivalent designation is CNMG120408PC TT8105B. Primary workpiece material is steel (ISO P group).

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Seat the insert fully against the toolholder pocket before tightening the clamp screw; an improperly seated insert can fracture under cutting load. Inspect the insert pocket and clamp for damage or debris before each insert change.
